How hard is it to get the blower wheel out of the housing?it vibrates more as you turn up the speed. maybe the wheel is fine and just out of balance.do i need to adress this asap or can i run the fan on low? i dont have a problem taking it to gm dealer but if i can do it in a timely manner i will do it in my garage. im a service tech for industrial heating an airconditioning company so i understand mechanics, controls, wiring etc. if you could help that would be great.
Re: ac blower wheel vibrating on 2002 gmc envoy slt!
If you remove the glove box, you can easily access the blower motor. The blower motor is held in by 3 bolts, 2 of the bolts are easy to get to, the third is a little more difficult. I had this same exact problem with mine and all I had to do was remove a bunch of leaves that got into it somehow, but I had all apart and back together within 2 hours, it may not have even been that long. Hope this helps ya.

It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.
check tyres for wear-wheel balance needed if visibly ok-have a wheel alignment after a tyre rotation-best even tyres to be put on fronts-they will carry out a safety check all suspension and steering before doing the wheel alignment
